The ZR LITE 31 System is approved and fully compatible with RVSM requirements on the Learjet 31. The incorporation of ZR LITE does not require any changes to the existing RVSM system and no additional calibrations are required.

Technology

Raisbeck Engineering developed the state-of-the-art composite flap kits, which are designed to attach to the flaps' forward spar and surrounding skins and structures.

The trailing edge flaps are re-contoured and twisted from -6 degrees (trailing edge up) at the wing root, to + 2.5 degrees at their outboard extremities.

The re-contoured flaps are more aerodynamically aligned where they meet the aileron. This removes the drooped ailerons' former discontinuity. Reduced drag and increased aileron effectiveness are the positive result of this new design.

The original trailing edge flap mechanisms are retained, while the flaps themselves have been removed aft of the flap spar and replaced with ZR LITE composite aft segments. They are protected from lightning and under-surface foreign object damage through the use of advanced materials.
